Be it known that I, JOHN LARRABURU, acitizen of the United States, residing at 'San Francisco, in the county-of San Fran' cisco and State of California, have"'nvented new and useful Improvements in\. Floors for. Bakers Ovens, otwhich the following is aspecification-- My invention relates to improvements in baking ovens in which is employed "Q mov- .able Hoor upon which the dou'glris' laced at one end and from which thdlie v'sare discharged at the other end, and ist-aldiyision of an application` Serial No. 891910,? by me April' '8th, 1915, and confined ,the

structure of the fiues oisaid oven, the pres ent application relatingr solely to the mow," able platform. T heobject of the invention" is to provide an oven of this character in which the movable Hoor shall be very firmly supported, especially at the center, notwith- In the accompanying drawing, h 'fi'gigure is a broken "side elevation of my improved baking oven, certain parts bei-ng shown 1n section: Fig. 2 is an enlarged broken side view of a movable Hoor; Fig. is a sectional view of the same; Fig. f1 .is a broken perspective view of a brick carrier detached 5 Fis-1'. 5 is a pereifnective view of a. link. l

The'boXesr 24 for the rear 'shaft 19 are drawn rearwardly by cables 32 passing oversuitably "mounted pullevs`33 and supporting weights 34.

Each brick is formed at its ends' with reccsses 68 to receive cementi'tiousmaterial, by which bripks in thel same brickcarrier lareca/ fised to adhere'to'each other,"and'said -'1. In a movable lf ioor for"bakers"ovens,
